As promised, the Mac I7 IDE is now available as a free download via the Mac App Store.
The version number is still 6L38 (although the store screenshots say 6L44?) Unless someone finds otherwise I’ll assume it’s the same compiler as the other 6L38 releases.
If you’ve already installed Inform (and you probably have if you’re reading this), then be warned: the App Store install process seems to like to find an existing install of the app and replace it. If you like keeping multiple versions around, maybe avoid this path.
